Question about Cars & Trucks
Need wiring diagrams in order to learn what is in the
circuit & how it works & were to do your testing
I think most people know that, but have no experience
working with wiring diagrams
I won't go near a vehicle or check anything at all, without
studying a wiring diagram first
You did the component testing part, but you usually do the
power or voltage drop testing & grounds to components first

The blower motor is connected to a termic switch, when the motor is fine and fuse is ok, is the switch that must be replaced.
Ensure the fuse is ok first.

This is from the A/C Module located under the dash passenger side, check wether the internal fan is working if it is, then change the Module which is a small black part with two white metal blades like... and your A/C should work again...

Check the dash fan control switch. It can be purchased separate from the whole cluster for under twenty dollars. The instrument panel cover comes off gently by hand with the tilt steering in the down position. You have to then unplug the electrical plugs to get it out of the way. The heater ac control panel then comes out by hand far enough to unscrew the heater fan control from the back. Auto Zone may have this part and have the step by step instruction to get the job done if needed. Good luck and hope this helps, if the fuse and relay is good, then it's going to be the switch. Keep me posted, be glad to help.
